Lung cancer is a cancer (malignancy) that originates in the tissues of the lungs or the cells lining the airways. Lung cancer originates when normal lung cells become cancer cells, usually after a series of mutations, and begin to divide out of control.
Lung Cancer is a disease which consists of uncontrolled cell growth in lung tissues. Lung cancer consists of two types, Non-small cell lung cancer, and small cell lung cancer. (NSCLC) is the most common type of lung cancer. The bronchi are the large air tubes leading from the trachea to the lungs that convey air to and from the lungs, and where most lung cancers begin. The body normally maintains cell growth only

The treatments for lung cancer depends on the stage and type of lung cancer and involves Surgery, Radiation therapy, Chemotherapy, Targeted therapy, and Lung cancer is usually treated with a combination of therapies in general. In surgery the tumor and the nearby lymph nodes in the chest are typically removed to offer the best chance for a cure. For non-small cell lung cancer, a lobectomy which involves the removal of the entire lobe where the tumor is located has shown to be very effective. Unfortunately, Surgery may not be possible in some patient due to the stage and type of lung cancer they have. Chemotherapy involves drugs used to kill cancer cells. A combination of medications is often used and may be prescribed before or after surgery, or radiation therapy. It can improve survival and lessen lung cancer symptoms in all patients, even those with widespread lung cancer. Radiation therapy contains the use of high-energy x-rays or other particles to destroy cancer cells. Side effects include fatigue, malaise, loss of appetite, and skin irritation at the treatment site. Radiation pneumonitis is the irritation and inflammation of the lung, which occurs in 15% of patients. It is important that the radiation treatments avoid the healthy parts of the lung.
Lung Cancer Staging is a way of describing a cancer, such as the size of the tumor and where it has spread. Staging is the most important tool doctors have to determine a
What are lung cancers? Lung cancers are the abnormal cells which grow in uncontrolled manner in one or both lungs. They do not function as normal lung cells and do not develop into healthy lung tissue. The abnormal cells can grow, form tumours and interfere with the normal functions of the lung (Lungcancer.org, 2015). Lung cancers can be divided into two major types, namely non-small cell lung cancers (NSCLC) and small cell lung cancers (SCLC). NSCLC can be further classified into three main subtypes, namely adenocarcinoma, squamous-cell carcinoma and large-cell carcinoma (Longo & Harrison, 2012). Lung cancers can be diagnosed by chest X-ray, computerised tomography (CT) scan, positron emission tomography-computerised tomography (PET-CT) scan, bronchoscopy and biopsy (Nhs.uk, 2015). Unfortunately, lung cancers are often diagnosed at the later stages. This is due to the unrecognisable symptoms and warning signs at the earlier stages. NSCLC are often diagnosed at stage IV which accounts for 30-40% of cases whereas 60% of SCLC is diagnosed at stage IV. Lung cancer usually originates from the cells lining the bronchi, bronchioles and alveoli. Carcinogens especially tobacco smoke will alter the gene expression of the normal human lung cells, resulting in cell mutation. The proto-oncogenes will be converted to mutated form, oncogenes. Mutation leads to the decreased expression of the tumour suppressor genes. This results in uncontrolled cell proliferation, cell
Lung cancer is a cancer that originates in the lungs. Lung cancer often goes undetected in the early stages, since symptoms don't usually present themselves until the advanced stages of the disease.
There are different types of lung cancers. NSCLC occurs when abnormal cells grow uncontrollably. The abnormal tissues multiply, and they form malignant tumors. The tumors can spread to other organs and tissues. Smokers have the highest rates of NSCLC. Prolonged exposure to radon can also cause NSCLC.
Lung Cancer, like any other type of cancer, is the uncontrollable growth of cells in the lung tissue. The main causes that contribute to lung cancer include inhaling carcinogens (basically, smoking), exposure to ionizing radiation, viral infections and even air pollution. These factors basically damage the tissues lining the bronchi in the lung, leading the cancer to develop further (Vaporciyan & Nesbitt JC, 2000). Primary lung cancers that develop in the epithelial tissues of the lung are known as carcinomas and claim the top spot in terms of leading cancer-related death causes. As of 2004, lung cancer
Cancer, it can affect anyone; it can affect any part of the body but what is it? Cancer results from the abnormality in the body's cells. This occurs when the cells divided and grow. Disruption in the system of the growth and division of a cell results in an uncontrolled division and proliferation of cells that form a mass which leads to cancer. The patient outcome for cancer is different for everyone, but it is also different with each type. In the respiratory department, a major type of cancer we will deal with is lung cancer. Lung cancer, however, has different types and stages, but for this paper, we are going to talk about Stage IIIA non-small cell lung cancer (NSCLC). In the article titled “Stage IIIA Non-Small Cell Lung Cancer” it states
Beneath the lungs, a slender, arch formed muscle called the stomach isolates the mid-section from the guts. When you inhale, the stomach climbs and down, compelling air all through the lungs. Lung tumor begins when cells of the lung get to be anomalous and start to become crazy. As more disease cells create, they can frame into a tumor and spread to different regions of the body. Non-little cell lung growth is a gathering of lung tumors that act likewise, for example, squamous cell carcinoma and adenocarcinoma. Side effects are a hack that won't leave, shortness of breath, weight reduction, or hacking up blood. Medicines incorporate surgery, chemotherapy, and radiation. Lung disease begins when cells of the lung get to be strange and start to become crazy. As more malignancy cells create, they can frame into a tumor and spread to different ranges of the body. Around 80% to 85% of lung growths are non-little cell lung malignancy (NSCLC). There are subtypes of NSCLC, which begin from various sorts of lung cells. Be that as it may, they are assembled together as NSCLC on the grounds that the way to deal with treatment and guess are regularly
Staging is used to locate cancer and to see if it's affecting any parts of the body. Doctors use staging in order to understand what stage of lung cancer a patient has. Once the stage is determined doctors will figure out what she should be used to cure the cancer. Lung cancer is different in each person, and treatment works differently for each tumor. Stages are determined by the size of the tumor, the location of the tumor, and whether the cancer has spread throughout the body. The first stage is stage 0. This stage means that the cancer is in place and it has not moved through the body. The
Stage 2 and Stage 3 cancer has invaded the chest (if large tumors are present its stage 3)
Lung cancer is a type of cancer is found in men and women lung cancer have something to do with your lungs. Your lungs which help pump oxygen into your body and also release carbon out of your body which helps you live because you need oxygen. Lung cancer is a common cancer in ages 60 and up it can also be found in any age but is most commonly in 60 year olds and older. Lung cancer is the leading cause of cancer deaths in the U.S. in both men and women. Lung cancer is also one of the most preventable kinds of cancer, but smoking is mainly the leading cause of lung cancer.
Lung cancer takes many years to develop. The characteristics of lung cancer the same as any type of cancer but it effects the lungs. Lung cancer is caused by expose to carcinogens
Brief Description: Lung cancer, as with all cancers, is an uncontrollable increase of cells. It happens within the lung tissue, but it could also go on to affect other nearby tissue and spread to further out than just the lungs.
Cancer can be one of the hardest battles that one must face, whether that battle is lost or won, it changes the lives of everyone involved. Lung cancer is one of the most diagnosed cancers and it affects the lining of the lungs and the ability to breathe. Lung cancer is the number one killer of men and women than any other cancer worldwide. This cancer is mostly found in smokers and this is why professionals are targeting this population for testing for diagnosing early and possibly saving a life (www.ncb.nlm.nih.gov). Lung cancer refers to the malignancies that originate in the airways or pulmonary parenchyma.
According to the American Cancer Society, lung cancer is the most common type of cancer in the world and has a mortality rate higher than colon, prostate, ovarian, and breast cancers combined.1 There are 3 types of lung cancer including non-small cell lung cancer, small-cell lung cancer, and lung carcinoid tumor. Approximately 85% of lung cancer cases are non-small cell, which include subtypes of squamous cell carcinoma, adenocarcinoma, and large cell carcinoma.2 Although less common, making up 10-15% of lung cancers, small-cell lung cancer is known for its rapid growth and spread.2 The types of lung cancer vary greatly in the prognosis and management of disease, as rate of growth, risk of metastasis, rate of recurrence, and treatment options are different with each.2 Physical therapy serves an integral role in the management of patients with lung cancer by providing interventions to optimize pulmonary and cardiovascular function.
Lung cancer is any type of cancer that begins in the lungs, although it is still considered lung cancer after it spreads to other parts of the body. Lung cancer is one of the most common cancers in the U.S. and worldwide. Forty percent of people will be diagnosed with lung cancer within their life span. Lung cancer, as with all cancers, is very complex, so the best way to comprehend it is to break it down into easily analyzed topics. The first topic that must be analyzed is cancer as a whole-what it is, what causes it, and what can be done about it. After this essential knowledge is gained, it is possible to analyze lung cancer from an informed angle, understanding the statistics, research, and various classifications. Lung cancer is
In summary, lung cancer is defined as abnormal cell tissue that forms in tissues of the lungs. There are three major types of lung cancer. It is known as non small cell, small cell, lung Carcinoid tumor. In addition, there are several options of treatment and are as follows: Surgery, Chemotherapy, Radiation Therapy, Immunotherapy and Vaccine Therapy. Caregivers can help direct patients through this process. It is key to have education, marketing awareness about health benefits of not smoking and read RJR and other tobacco company information to be inform.
